Given a and b are numbers, and a + b = 180, which statements also must be true?
(1.) Name a pair of the following angles;
(a.) Complementary angles.
(b.) Supplementary angles.
(2.) Make a conjecture about the relationships between angle measures at an intersection.
Find Missing angles.
The two lines below intersect. Find the value of b and c.
(1.) Angle b = ?
(2.) Angle c = ?
In the figure above, angles R and S are complementary.
(1.) Find the measure of angle S.
(2.) If two angles are both vertical and supplementary, can we determine the angles? Is it possible to be both vertical and complementary?
(3.) If so, can you determine the angles? Explain how you know.
